During rush hour where I live (NYC), hundreds and hundreds of people ride the same bus I do. If each group of ~4 had their own car, everything would break down, and I shudder to think of the impact on the environment.
The main problem w/ the model is people having to travel non-walkable/bikeable distances twice a day. Until we invent teleportation, not a lot is gonna change that basic math.
- CuriouslyC 7y agoNew York is a special case and you can't use it to make general statements about transportation at all. Due to its density, not owning a car is pretty common in NYC, but unheard of elsewhere in the US. The vast majority of the population lives in low or medium density places where mass public transportation is a huge waste of time and effort.
- camgunz 7y agoI think you're missing my point(s) a little. Most of the important tradeoffs between public transportation and individual automobiles are the same no matter the density, and it's all a function of how many people are "on the road" at a given time. You can cram 'em onto buses, or deploy a fleet of rideshares, but the core problem is moving billions of people non-walkable/bikeable distances twice a day. Grandparent's point was self-driving cars solves the labor problem, and thus the benefits of ridesharing totally outshine the benefits of mass transit. I'm saying I don't think a labor shortage is the main problem (no matter how much you think those drivers are making, it's not a lot). Rather, I think the problem is "every American worker gets a car and is transported ~16 miles twice a day" isn't scalable.
- djannzjkzxn 7y agoTo be clear, I think self-driving cars beat busses on quality of service. There simply isn’t a bus that exists that will take most people from where they are where they want to go. Dynamically generated routes beat fixed routes, because they get people to their destination. UberPool accomplishes the same thing, but uses more drivers per passenger than a bus, which leads to labor exploitation. Self-driving fixes that problem. And no, I don’t want to shut down the busses. I’m describing why so few people are using them, and why self-driving cars have a better chance of success. In fact, I think self-driving is a necessary ingredient for a public transit system that meets everyone’s needs in the US. I think buses are a natural park of a self-driving network - a dynamic dispatch system can use them on the most in-demand routes. Right now in America, the vast majority of people are driving solo to work. Even if self-driving vehicles merely double the capacity those vehicles handle, that seems enough to fix our transit problem.
- camgunz 7y ago> To be clear, I think self-driving cars beat busses on quality of service. Yeah if your metric is how much time you spend walking, or privacy I guess, then a car is better than a bus (a car with no driver even more so). But in NYC many people don't have cars, and while "parking in the city is impossible" is one reason, there are other way more popular ones: - mass transit is much, much safer - it's more environmentally friendly - it's faster (trains, not buses, although with bus lanes and lights that might be changing) - car maintenance is expensive and tedious - cars are expensive assets that depreciate incredibly fast - you can do other things while on mass transit > There simply isn’t a bus that exists that will take most people from where they are where they want to go. You might be surprised. There's a bus around the corner from me that takes me directly to my subway station. My total walk time is maybe 2 minutes. It doesn't make any sense to me to figure out self-driving cars to save me 4 minutes of walking a day, in fact that's probably a bad idea and pattern in general. > I’m describing why so few people are using them, and why self-driving cars have a better chance of success. Again you might be surprised. In NYC, 2.25 million people ride the bus every weekday. I don't know what rideshare stats are, but I bet they're lower. In places without expansive and deep mass transit systems, people don't ride buses for exactly the reason you said. But the answer isn't to figure out self-driving cars, the answer is more buses (and other vehicles like light rail), drivers, and routes. > In fact, I think self-driving is a necessary ingredient for a public transit system that meets everyone’s needs in the US. Well, it doesn't exist at all right now, so I think that's pushing it when it comes to "needs". Something else that would satisfy that is if we installed light rail and started switching wholesale to remote work, things we know how to do super well right now. It's also even safer than self-driving cars, easier on the environment, cheaper, etc. Self-driving cars remind me a lot of blockchain: a solution looking for a problem. It's a little more vexing than blockchain though, because commuting really seems like a drive time problem, but the root problem there isn't that a working human has to drive, it's that a working human has to move 30 miles every workday. The smart, efficient solution here is better mass transit and more remote work.

If each group of ~4 had their own car, everything would break down, and I shudder to think of the impact on the environment. You're forgetting the other half. What if we remove 3/4 of the existing car volume at the same time? > and I shudder to think of the impact on the environment. Despite it being electric?
- camgunz 7y agoWhat do you mean reducing car volume? You asymptotically approach "bus" the more people you put in a vehicle. Turning one bus that holds ~50 people into 12 smaller buses that each hold 4 people doesn't solve anything as far as I can see. Re: electric, this is a good step but we still produce most of our electricity (by far) by burning fossil fuels. Plus we lose energy in transmission/storage so it's a net loss.
- Dylan16807 7y agoWhy are you ignoring all the traffic right now that isn't busses? Let's say we currently have one bus and twenty cars. If we replace that with 12 vans and 5 vans, respectively, that leaves us with 17 vans. The road is now less congested and less polluting. (There's no reason to expect all the current cars to be replaced, but there's no reason to expect all the busses to be replaced either.)
- camgunz 7y agoI guess I'm not super interested in the pretty small difference between van and bus. Grandparent's point was cars are better because they don't make a bunch of stops and they don't wait for people to get on/off. As you add people into vehicles you lose those advantages, but you lower your overhead. But as more and more people work (global population is still increasing), this doesn't scale. Commuting is the problem, not humans having yet to find the perfect commuter to axle ratio. This is my problem with self driving tech in general. So much energy and engineering has gone into solving a problem we don't need to solve. The answer is more light rail and more remote work. And if you think it's a tech solution to a political problem, I'd point you to all the political problems Uber is having. It's just, idk bad planning or something.
